In the biggest fight of the week, Kell Brook defends his IBF World Welterweight title against unbeaten American Errol Spence Jr, at Sheffield United's Bramall Lane. George Groves fight Fedor Chudinov for a world title for the fourth time, while Dave Allen, Jamie Cox and Olympian Anthony Fowler are also on the bill.

Steps will be taken over the coming days to increase security around all the forthcoming fight week events. Saturday night will see an increased police presence. Full body searches will be undertaken on entry to the stadium and no bags will be allowed inside. As a result, fight fans are being advised to allow extra time to attend the event.

Brook will be making the fourth defense of his IBF belt against Spence, who is the mandatory challenger and one of the most highly regarded contenders in the sport today. Spence is a -225 favorite to dethrone Brook +175, even though Brook is the local favorite.
